1. And specific questions? If not, decimal division. If a decimal is divided by a decimal, the divisor and the divisor can be expanded by the same multiple according to the number of decimal places of the divisor. For example, if the divisor is one decimal place, the divisor and the divisor can be expanded by 10 times at the same time, the divisor is three decimal places, and the divisor and the divisor can be expanded by 100023 times at the same time. The divisor can be changed into an integer, and then calculated according to the vertical formula of integer division. In Grade 5, I have learned fractions. At the same time, I expand the divisor and the multiple of the divisor. The quotient remains unchanged, which is the same as the general rules of fractions

2.

6 ÷ 12 as an example. The steps are as follows:

Step 1: because the divisor 0.12 has two decimal places, the divisor and the divisor are expanded by 100 times (that is, 1260) ÷ 12) The decimal point of 0.12 is eliminated and written into the vertical division. As shown in the figure:

3. The checking method of decimal division:
1 × Divisor = divisor (general)
② divisor ÷ Quotient = divisor
e.g. 15 ÷ 3 = 5. It's whether quotient times divisor equals divisor. Results of checking calculation 3 × 5 = 15, or 15 ÷ 5 = 3. After the problem is solved, the inverse operation (such as addition for subtraction and multiplication for division) is used to check whether the result of previous operation is correct
extended data
1. Calculation method of decimal division when divisor is an integer: divisor is a decimal division of an integer, which is removed according to the rule of integer division, and the decimal point of the quotient should be aligned with the decimal point of the divisor; If there is a remainder at the end of the divisor, add 0 after the remainder and continue the division
2. Divisor is a decimal division algorithm: divisor is a decimal division, first move the decimal point of divisor to make it an integer; The decimal point of the divisor moves several places to the right, and the decimal point of the divisor also moves several places to the right (if the number of digits is not enough, use 0 to make up at the end of the divisor), and then calculate according to the decimal division method in which the divisor is an integer
3. The formula of continuous division can be written as the proct of the divisor divided by several numbers, but when dividing by the proct of several numbers, you must add parentheses to the multiplication formula
4,
the discovery in decimal division:
when the divisor is not 0 and the divisor is greater than 1, the quotient is less than the divisor. For example: 3.5 ÷ 5 = 0.7
when the divisor is not 0 and the divisor is less than 1, the quotient is greater than the divisor. For example: 3.5 ÷ 0.5 = 7
when the divisor is not 0 and the divisor is equal to 1, the quotient is equal to the divisor. For example: 3.5 ÷ 1=3.5

4. Divisor is a decimal. The calculation of decimal division is based on
divisor is the division of decimals. According to the property of quotient invariance, the divisor (with divisor as the standard) and the divisor are expanded by the same multiple at the same time. The divisor is converted into an integer, and then calculated according to the division rule that divisor is an integer.

so the answer is: the property of quotient invariance

6. Divisor is the decimal division of an integer. First, the quotient is calculated according to the integer division, and the decimal point of the quotient is aligned with the decimal point of the divisor; Divisor is a decimal division of decimals. First, the divisor is changed into an integer. The decimal point of the divisor is moved to the right by several digits, and the decimal point of the divisor is also moved to the right by the same digits (when the digits are not enough, 0 is used to make up). Then, the calculation is carried out according to the decimal division of the divisor as an integer

how is the algorithm of decimal division defined
(1) division of decimals whose divisor is an integer
division of decimals whose divisor is an integer can be calculated according to the following steps:
1
2. The decimal point of quotient should be aligned with the decimal point of divisor
③ when there is a remainder at the end of the divisor, add 0 after the remainder and continue to divide
example 1: 117 ÷ 36 = 3.25

(2) divisor is the decimal division of decimal
divisor is the decimal division of decimal, which can be calculated according to the following steps:
first remove the decimal point of divisor to make it an integer
② to see how many decimal places the divisor has, move the decimal point of the divisor to the right by the same number of decimal places (fill in 0 if the number of decimal places is not enough)
③ calculate according to the division of integer divisor

(3) the approximate value of quotient
in real life and proction, we often encounter that the decimal division can not be divided completely or the number of decimal places of quotient is too much, but it is not needed in practice. We can take the approximate value of quotient according to the requirements and specific circumstances
example 3: 122 ÷ 16 ≈ 7.6 (keep one decimal place)

take it for me, thank you~

7. There are four types of decimal division
1, integer divided by integer
for example: 12 ÷ 16，43 ÷ 25，33 ÷ 28...
2, decimal divided by integer
for example: 12.45 ÷ 23，4.4 ÷ 8，23.3 ÷ 3...
3, integer divided by decimal
for example: 24 ÷ 1.4，43 ÷ 0.8，77 ÷ 2.54...
4, decimal divided by decimal
for example: 8.8 ÷ 2.6，3.25 ÷ 0.2，6.7 ÷ 1.5...
decimal division is calculated according to the method of integer division. As long as the latter two methods are changed into the problem that divisor is an integer, they can be calculated. It should be noted that the decimal point of the quotient is aligned with the decimal point of the divisor, and the division can continue when there is a remainder

operational properties of division
1. The divisor expands (shrinks) n times, the divisor remains unchanged, and the quotient expands (shrinks) n times correspondingly
2. Divisor expands (shrinks) n times, divisor remains unchanged, quotient shrinks (expands) n times correspondingly
3. The divisor divided by two divisors is equal to the proct of the two divisors
sometimes we can perform simple operations according to the nature of division. For example: 300 ÷ twenty-five ÷ 4=300 ÷ twenty-five × 4) Divide by a number = the reciprocal of the number
